Your Mustang is puffing black smoke???? 3 yrs old, hmmm..... blue smoke or black smoke? black smoke is just running rich, blue smoke is bad news. Fix your car (its practically new), save your money and put an ATI Procharger on that 4.6. You won't have to worry about any foreign cars making you look silly after that, for sure //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
And dude, the sound that 4.6 will make with flowmasters and x-pipe, notwithstanding the whistle from the procharger. why would you want anything else????
Forget about your audio system, you will never turn it up, that car will sound SWEET. And it gets around 25 mpg. you're talking highway miles to school, right? Your not going to do much better with a 4.turbo.
Seriously considering one myself.
I've been trying to get my fiance to purchase a WRX, that would be my second choice, for a lowcost "no maintenace", "safe driver". I could really look into hot-rodding one of the new gen turboed. You know, for my GIRLFRIEND and such. For me, I want a little rumble under my butt.
Of course, this is all just IMO!
